While a combination of cognitive behaviour therapy (CBT) and psycho-pharmaca seems successful for 50% to 60% of patients, for intractable cases the typical recommendation is more medication or more CBT, however there is little evidence that the intensi- fied treatment regimen is successful. In this paper, habit reversal training, including awareness training, competing/other response training, self-monitoring, social support, and generalisation, was implemented with a long-term treatment-refractory OCD patient. Treatment gains and long-term maintenance indicate the potential of habit reversal procedures with these patients. Key words: Obsessional-compulsive disorder, habit reversal, relaxation, evidence-based practice, men- talism, CBT. According to the DSM-IV the diagnosis of person is aware that their behaviour is unusual Obsessive-Compulsive Disorder (OCD) is based (BABCP, 2004). Consequently, OCD can become on two components. “Obsessions are constant, in- a source of significant embarrassment and humili- trusive, unwanted thoughts that cause distressing ation and potentially interferes with general daily emotions.
